No, that’s not what caused it. What probably happened is your log4j2.xml file got updated after the upgrade. There were required changes to the logging config a lot of people where missing because they kept their old configs instead of adopting the new ones.
It’s based on the name of the logger and you are explecitely setting that name to “org.openhab.model.script.Rules.Update_Regen_24hrs”.
Assuming you use the same naming scheme in all your rules, set the level for “org.openhab.model.script” and it should change it for all your rules.
